Ball Drilling Specifications

The ITBA would like to remind members that the rules regarding Ball Weight and Drilling have been amended due to a mandatory change introduced by the USBC/IBF/ETBF.

Due to the impact of Covid-19 we had extended the initial introduction of this new ruling but feel there has been enough time since August 2020 for bowlers to make sure their equipment complies with the current specifications.
